In her second official appearance of the year, the Duchess of Cambridge stepped out on Tuesday morning—alongside Prince Harry and Prince William—for an event held at London’s Institute of Contemporary Art, where the trio spoke about their work with the organization Heads Together, their campaign focusing on mental-health issues.

Each of the three royals spoke briefly about mental health, meaning, yes, this engagement featured a rare Kate speech! (“The question that William, Harry, and I have asked ourselves is, How can we get more people to start talking [about mental health]? How do we encourage people to take the first step?” Kate asked in her speech.)

Kate wore a dress from Erdem—a favorite designer of hers—for the occasion, which the Mirrorhas deemed “winter floral,” given the outfit’s floral overlay and black color. (The dress sells for about $1,300.) The description of the dress—called the “Evita Black Lily Collage” dress—on the Erdem site refers to it as “transitioning effortlessly between seasons as it does from day to evening.” Convenient!

Meanwhile, unsurprisingly, no sign of Meghan Markle—girlfriend to Prince Harry—at the event. The two are reportedly “chilling and enjoying lazy days together” in London, ever since returning from their Norway New Year’s vacation.

“How did it go?” we imagine Markle, working on a balsamic salmon recipe, asking Harry as he returns from the engagement.

“Oh, you know,” Harry would respond, loosening his tie, flashing a smile. “Just another day at the office.”

JANUARY: We begin 2016 with some strong, intricate bun action. She looks like a chic character in a British spy movie here.

FEBRUARY: Sometimes it’s as if her hair has its own motivations and agency, isn’t it? Here, in February, her hair seemed to be feeling particularly lively.

FEBRUARY: Maybe it’s the contrast with the green outfit, but the color here is extra luminous. This is the sort of hair day where you bank a bunch of selfies to save up for posting on later dates.

FEBRUARY: Kate in athletic tennis mode is still somehow more effortlessly glam than our, like, most formal black-tie look would be.

NOVEMBER: “Oh, you want to take a photograph of me? Didn’t realize . . . just kidding, I realize. Do it now, let’s go.”

DECEMBER: A tiara look is a rare occurrence for Kate, and one that should not be taken for granted! (This is only the fifth time since she married William that Kate has worn one.)

DECEMBER: We end with a causal Kate look, which—even given its low-key vibe—still looks like it could be part of a Vogue pictorial.

MARCH: There’s a sort of chunky semi-bangs situation going on here, and it is very successful.

MARCH: This is a very intense hat. It’s huge! This is the sort of hat you wear when you’re not super-psyched about how your hair looks, so you just toss a big hat over it all before you go outside. (Though, in Kate’s case, we’re sure it still looked amazing under the hat.)

APRIL: Here she is, deplaning in India, looking as fresh-faced as most people would on their wedding day.

APRIL: It’s no small feat keeping one’s composure around Michelle Obama to begin with—to do so while looking like you could be posing for a magazine cover yourself is a real accomplishment.

MAY: Part of her hair is going rogue here, which is nice because it helps us to remember Kate is human—though, at the same time, that it almost doesn’t even register in any way as off just reaffirms her superhuman-ness.

MAY: We can’t even see the bun happening on the back of her head here, but we feel very confident in saying it looks incredible.

MAY: This is up there with our top Kate looks from the past few years. Sophisticated, modern, and with a touch of intrigue.

MAY: She looks like she could be one of the Avengers here, no?

JUNE: Her hair here—for a June function—is not calling a lot of attention to itself, but it’s giving us some Farrah Fawcett vibes, which we very much enjoy.

JUNE: Kate holding a glass of champagne—in an all-time-classic Middletonian gown, a repeat from 2011—makes this one of the more Platonic Ideal Kate photos. This should honestly be subbed in as her Wikipedia entry photo.

JULY: At Wimbledon, this Vivacious Chestnut hair color is very much popping against her yellow dress.

JULY: Can you imagine if royals were allowed to do brand endorsements and Kate filmed a commercial for L’Oreal or Pantene or one of the major brands?! It would be the end of celebrity hair commercials! No one could do any after that!

JULY: George is working to pull focus here, but we have Kate Headband Hair here, and really nothing is capable of fully distracting from that.

AUGUST: Oh, this isn’t how your hair looks when you emerge from your car for an appearance in August humidity?

AUGUST: A different, more slicked-back look here. In our initial notes for this one, we wrote “RED SWEET HAIR LIFE,” by the way.

SEPTEMBER: What to even say about this one!?!?! It’s as if she has a personal wind fan in front of her at all times.

SEPTEMBER: All of Kate's Canada tour looks were immaculate, but we are particularly partial to this Cascading Locks meets Emerald Green effect.
